[Buildroot] [git commit] prosody: fix build with musl libc

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=286a81d7a267488a78c9fb85159fe8d85fa2bd76
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

musl libc does not provide the mallinfo() API. Define WITHOUT_MALLINFO
to skip the code using it.
